How to choose the air conditioner? Does it mean the higher the HP number, the higher the cooling capacity?
The cooling capacity of air conditioner is not reflected by HP number. By referring to the cooling capacity (kW) on energy label, you can choose a suitable air conditioner and compare the efficiency of power saving. For instance, an air conditioner of “First Class Energy Label” with 2.6 kW (1 HP) cooling capacity is relatively efficient in power saving than that of “Fifth Class Energy Label”.
If I replace my split type air conditioner, can I use the R22 refrigerant pipe in the split type air conditioner using refrigerant R410A?
If your original one is using R22 refrigerant, the refrigerant pipe must be replace by the new one with R410A refrigerant. The reason is that thicker tube wall of pipe is required to resist the higher pressure of “eco-friend” refrigerant, and the lubricating oil remains from R22 refrigerant pipe will damage your new air conditioner.
